Here is a MAHLI image of our second drill hole at Cumberland.  Like the first drill hole it shows the difference between the reddish uppermost surface of Mars and what lies underneath.  This drill hole area has a difference in that there are more unusual, rounded concretions than at the first site.  Their mineralogy is likely to be reflected in the CheMin and SAM analyses of the sieved powder.

There is a great video showing the sieving procedure at:
